Andre Stainless stands out as a top manufacturer and supplier of Stainless Steel 348 Flanges in Singapore, specifically in Pulau Ujong. They provide high-performance solutions tailored for industries that require exceptional heat and corrosion resistance. Built to endure high-temperature conditions, SS 348 flanges are perfect for applications in chemical processing, aerospace, and power generation. Andre Stainless offers a diverse range of flange types, including weld neck, slip-on, blind, and socket weld flanges, all crafted to meet international standards like ASTM A182 and ASME B16.5. With rigorous quality control and prompt delivery, Andre Stainless guarantees reliable performance and long-lasting durability in critical piping systems.
Stainless Steel 348 Flanges are crafted from a columbium-stabilized austenitic stainless steel that contains 17–20% chromium, 8–11% nickel, and small amounts of niobium (columbium), which boosts high-temperature stability. These flanges showcase a minimum tensile strength of 515 MPa, a yield strength of 205 MPa, and impressive elongation of 30% or more. The presence of niobium helps prevent carbide precipitation, providing excellent resistance to intergranular corrosion, particularly after welding. SS 348 flanges retain their mechanical strength and oxidation resistance even at elevated temperatures, making them ideal for continuous operation in heat-intensive settings.
